Produce washer

ABSTRACT

Produce, whether vegetable and/or fruit, is supported upon a screen basket suspended within a closed cabinet. Each of a plurality of nozzles disposed about the basket emits a filled cone of washing liquid to scour the produce and to dislodge by agitation and flotation debris therefrom. After filtering of the washing fluid through a screen in the cabinet, the washing fluid is recycled by a pump pumping the washing fluid from a collection trough to the nozzles. Preferably, the washing fluid is slightly acidic.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to washing apparatus and, moreparticularly, to apparatus for washing produce.

2. Description of Related Art

Washing machines for crockery have been available for years. Suchmachines provide racks for supporting the crockery on edge or invertedto encourage drip drying after the washing process. The cleaningfunction is performed in part by a plurality of nozzles, whetherstationary or moveable, which a spray pattern of fine water droplets inthe form of a hollow expanding cone with a relatively high impact force.The washing function is substantially aided by the use of very hot waterand the chemical deterging and degreasing properties of a cleaningagent.

For produce, including fruits and vegetables, a spray providing finewater droplets having a substantial impact force would bruise or damagethe produce and such sprays must be precluded. The use of a cleansingagent to wash produce would leave an unacceptable after taste unlessextraordinary and time consuming rinsing were incorporated. Moreover,the cleaning agent may produce an unacceptable chemical reaction withthe produce that would result in deterioration or damage of the produce.Finally, a high temperature washing fluid would wilt or otherwise damagethe produce.

The produce washers known provide a swirling immersion bath thatprovides a gentle rinse to the produce to prevent damage anddeterioration. Unfortunately, such gentle rinsing fails to clean thecrevices, interstices and other surface perturbations of the produce.Moreover, debris lodged within folds, in depressions or in cavities isusually not removed. Thus, such produce washers are primarily used foran initial washing operation to be followed by hand washing prior topresenting the produce for cooking or eating. Manually operated producewashers are also known and are effective to the extent an operatordiligently directs the washing fluid on and about the produce.

SUMMARY OF THE INVENTION

Produce is loaded upon a basket of mesh material placed within acloseable cabinet. A plurality of nozzles, which nozzles may be fixed ormovable, are located above and below and possibly on the sides of thebasket to direct sprays of washing fluid onto the produce; preferably,the washing fluid is slightly acidic. The nozzles are configured toprovide a non hollow expanding cone spray pattern to provide relativelylarge but slow moving droplets to gently agitate and to scour theproduce surfaces impinged. The large droplets tend to dislodge, floatand convey any liquid or solid debris on the produce. Because of therelatively low impact forces of the droplets, soft surface produce, suchas strawberries, may be washed equally as well as hard surfaced produce,such as celery. The washing fluid containing debris is filtered andcollected in a trough. A pump recycles the washing fluid from the troughthrough the nozzles for a period of time sufficient to complete thewashing process. After washing is complete, the washing fluid isdischarged. A rinsing fluid, such as tap water, is sprayed onto theproduce to rinse the produce and remove any residual washing fluid ordebris.

It is therefore a primary object of the present invention to provide awasher for washing produce of any type.

Another object of the present invention is to provide a produce washerfor washing robust and tender produce with equal effectiveness andwithout damage.

Yet another object of the present invention is to provide a producewasher for simultaneously washing a mixture of different produce.

Still another object of the present invention is to provide a producewasher for recycling the washing fluid.

A further object of the present invention is to provide a plurality ofnozzles for omnidirectionally spraying produce with a washing fluid.

A yet further object of the present invention is to provide stationaryand moveable nozzles for spraying produce with a washing fluid.

A still further object of the present is to provide a produce washerhaving a plurality of nozzles for emitting an expanding non hollow coneof droplets of washing fluid.

A still further object of the present invention is to provide a producewasher for washing produce of various kinds during a washing cycle andfor rinsing the washed produce during a rinse cycle.

A still further object of the present invention is to provide a methodfor washing produce.

These and other objects of the present invention will become apparent tothose skilled in the art as the description of the present inventionproceeds.

DESCRIPTION OF THE PREFERRED EMBODIMENT

A produce washer 10 housed within a cabinet 12 is illustrated in FIG. 1.The cabinet includes a closeable door 14 for providing access to theinterior of the cabinet to load and unload the produce to be washed. Abasket 16, formed of a mesh or other easily water permeable materialsupports and contains the produce to be washed. The basket is mountedupon opposed ledges 18, 20, which ledges may include rollers 22 orsimilar devices to assist in sliding the basket into and out of cabinet10. A shelf 24 extends across the lower end of compartment 26 defined bycabinet 10; the shelf may include one or more substantially sized holesor apertures 28 to accommodate drainage of washing fluid. A filter 30 isremovably lodged or mounted beneath shelf 24 to filter debris from thewashing fluid flowing through aperture 28. Preferably, a cutout switch(not shown), such as a magnetic switch, is enabled upon mounting of thefilter to prevent operation of the produce washer unless the filter isin place. A control panel 32 is mounted on the exterior of cabinet 10 toprovide start, stop and other controls for operation of produce washer10. Moreover, it may include timers to vary the time of fluid flow,pressure controls in combination with pressure gauges to vary thepressure of the fluid flow, and flow controls to vary the quantity offluid recycled.

Referring jointly to FIGS. 2, 3 and 4, further details of produce washer10 will be described. Cabinet 12 includes side walls 40, 42, rear wall44, top 46 and bottom 48. Compartment 26 is defined by false side walls50, 52, false rear wall 54, false top 56 and false bottom 58. The spacesintermediate compartment 26 and cabinet 12 are used for routing plumbingand electrical conduits, as illustrated in part in FIGS. 2, 3 and 4.

Filter 30 is supported upon shoulders 60, 62 extending inwardly fromfalse side walls 50, 52. A further shoulder 64 for supporting the rearedge of the filter may extend from false rear side wall 54. Upon closingof door 14, the door engages seals 70, 72, 74 and 76 extending aboutopening 78 to compartment 26. Thereby, upon closing the door,compartment 26 will become essentially watertight. False bottom 58serves in the manner of a trough 80 to collect the washing fluid. Itincludes a downwardly extending cone shaped drain 82 for discharging thewater. An electrically actuated pump 84 includes a conduit 86 extendingfrom inlet 88 in fluid communication with drain 82 to draw water fromtrough 80. Outflow from pump 84 is conveyed via conduit 90 to a conduittree 92 for discharging water through a plurality of outlets or nozzlesinto compartment 26. Conduit 94 of the conduit tree extends beneathshelf 24 and upwardly through aperture 28. An arm 95, including nozzles96, 98 is rotatably mounted at the end of conduit 92 to locate the armwithin compartment 26 and beneath basket 18. Mounting 100 accommodatesrotatable movement of arm 95 and also accommodates flow of washing fluidfrom within conduit 92 into the arm for expulsion through nozzles 96,98. The spray pattern of the nozzles is directed upwardly into basket18. Conduit 110 of conduit tree 92 conveys washing fluid through anaperture in false top 56. An arm 112, supporting nozzles 114, 116 isrotatably mounted by mounting 118 at the terminal end of conduit 110.The mounting accommodates rotation of the arm and accommodates flow ofwashing fluid from conduit 110 into the arm for expulsion throughnozzles 114, 116. The washing fluid sprayed from the nozzles is directeddownwardly into basket 18. Nozzles 96, 98 are mounted upon arm 95 at anangle of the vertical axis to provide a reaction force upon expulsion ofthe washing fluid to induce rotation of the arm, as depicted by arrow102. Similarly, nozzles 114, 116 are mounted at an angle off thevertical axis to provide a reaction force upon expulsion of washingfluid to induce rotation of the arm, as depicted by arrow 120. Thecanting of the nozzles is represented by canted nozzle 114 attached toarm 112 as depicted in FIG. 2a. As particularly depicted in FIGS. 3 and4, a plurality of nozzles 96 and 98 may be mounted upon arm 95.Similarly, a plurality of nozzles 114, 116 may be mounted upon arm 112.It is understood that a seal 122 may be disposed between conduit 110 andfalse top 56 to preclude water flow therebetween. Similarly, a seal 104may be disposed about conduit 92 in false rear wall 54 to prevent waterflow therebetween.

As particularly illustrated in FIGS. 3, 4 and 5, conduit tree 92 mayinclude a drain conduit 130 and valve 132 controlling outflow throughthe drain conduit. Thereby, pump 84 may also be used to drain trough 80on completion of a washing cycle. Water inlets 132, 134 are in fluidcommunication with trough 80 to accommodate inflow of washing fluid. Oneof these inlets may be connected to a source of water at ambienttemperature and the second inlet may be connected to a source of chilledwater at a predetermined temperature. Alternatively, one of the inletsmay be used to introduce an additive, such as a weak acidic solutionwhich is beneficial for cleaning various types of produce.

Referring to FIGS. 6 and 7, there is illustrated an alternate embodimentof conduit tree 92 which conduit tree 140 provides a plurality of fixednozzles for spraying a washing fluid upon the produce to be washed. Theconduit tree includes arms 142, 144 terminating in nozzles 146, 148,respectively. A further nozzle 150 is disposed at the junction of thearms and a nozzle 152 is disposed at the bend of arm 144. Each of thesenozzles extends through false top 56 in sealing engagement therewith toprevent water flow upwardly therebetween. Nozzles 146, 148, 150 and 152direct washing fluid downwardly into basket 18 within compartment 26.Similarly configured arms 154, 156 are disposed beneath shelf 24 andsupport four nozzles in the manner of arms 142, 144 and of which nozzles158, 160 are illustrated. The four nozzles extending through shelf 24emit an upwardly directed spray of washing fluid into basket 18.

A complex conduit tree 170 is illustrated in FIGS. 8, 9 and 10. Aconduit tree of this type provides a plurality of downwardly directednozzles, upwardly directed nozzles, inwardly directed nozzles fromopposed sides and nozzles located within compartment 26 to spray waterboth upwardly and downwardly simultaneously. A complex conduit tree ofthis type is particularly useful when a pair of spaced apart baskets(242, 244) are located in the compartment within the cabinet. Conduittree 170 includes a manifold 172 connected to the outlet of pump 174,which pump draws washing fluid from a trough at the bottom of thecabinet through inlet conduit 176. An upright conduit 178 extends frommanifold conduit 172 and supports laterally located arm conduits 180,182. Arm conduit 180 supports one or more laterally directed nozzles184. Similarly, arm conduit 182 supports one or more laterally directednozzles 186. An arm conduit 188 extends from upright conduit 178 andsupports one or more upwardly directed nozzles 190. Another arm conduit192 extends from upright conduit 178 and supports one or more downwardlydirected nozzles 194 and one or more upwardly directed nozzles 196. Afurther arm conduit 198 extends from upright conduit 178 and supportsone or more downwardly directed nozzles 200. Nozzles 202 may be mountedupon upright conduit 178 to direct washing fluid laterally. An uprightconduit 204 extending from manifold conduit 172, supports lateral armconduits 206, 208. One or more nozzles 210 may be mounted upon lateralarm conduit 206 to direct washing fluid laterally. Similarly, one ormore nozzles 212 are supported by lateral arm conduit 208 to directwashing fluid laterally. Arm conduit 214 extends from upright conduit204 and supports one or more nozzles 216 to direct washing fluidupwardly. Arm conduit 218 extends from upright conduit 204 and supportsone or more nozzles 220 to direct washing fluid downwardly and one ormore nozzles 222 to direct washing fluid upwardly. Arm conduit 224 alsoextends from upright conduit 204 and includes one or more nozzles 226 todirect washing fluid downwardly. One or more nozzles 228 may be disposedalong upright conduit 204 to direct washing fluid laterally.

FIGS. 9 and 10 illustrate a cabinet 240 for housing a conduit tree, suchas conduit tree 170 illustrated in FIG. 8, and a pair of baskets 242,244. Basket 242 may be supported upon ledges 245, 246 and rear ledge 247and basket 244 may be supported upon leges 248,249 and rear ledge 250. Adoor 252 provides access to interior compartment 254 defined by falseside walls, top and bottom, as described above with reference to cabinet12. A shelf 256 includes a central aperture 258 to accommodate drainageof the washing fluid. Additional apertures, of which apertures 260, 262and 264 are shown, may encircle nozzles 190, 216 extending upwardly fromarms 188, 214, respectively. Washing fluid flowing through the aperturesin shelf 256 is filtered by filter 270. A trough 272 is disposed beneaththe filter to catch and collect drained washing fluid. A cone 274provides for discharge of the washing fluid from trough 272 into inletconduit 176 and to pump 174. As illustrated in FIGS. 9 and 10, theconduits forming conduit tree 170 may be disposed in the spaces betweenthe false walls defining compartment 254 and the exterior walls ofcabinet 240. Preferably, seals are provided about each of the nozzlespenetrating the walls of compartment 254 to preclude inadvertent waterflow therebetween.

As particularly noted in FIGS. 8 and 9, nozzles 200 provide a cone ofspray 280 downwardly upon and into 242. A similar cone of spray 282 isprovided by nozzles 226. A cone of spray 284 is provided by nozzles 186laterally upon and into basket 242. Nozzles 184 provide a cone of spray286 laterally upon and into basket 244. Nozzles 210 provide a cone ofspray 288 laterally upon and into basket 244. Nozzles 212 provide a coneof spray 290 laterally and upon basket 242. Nozzles 196 provide anupwardly directed cone of spray 292 upon and into the bottom of basket242. Nozzles 222 provide an upwardly directed cone of spray 294 upon andinto the bottom of basket 242. Nozzles 194 provide a cone of spray 296upon and into the top of basket 244. Nozzles 220 provide a cone of spray298 upon and into the top of basket 244. Upper ones of nozzles 202provide a cone of spray laterally and forwardly upon and into the rearof basket 242. Similarly, upper ones of nozzles 228 provide a lateralcone of spray upon and into the rear of basket 242. Lower ones ofnozzles 202 provide a lateral cone of spray upon and into the rear ofbasket 244. Similarly, the lower ones of nozzles 228 provide a cone ofspray laterally upon and into the rear of basket 244. Nozzles 190provide a cone of spray 300 directed upwardly upon and into the bottomof basket 244. Nozzles 216 provide a cone of spray 302 directed upwardlyupon and into the bottom of basket 244.

Upon inspection, it will become evident that the nozzles attendantconduit tree 170 spray both baskets 242, 244 from the top, bottom theopposed sides and the rear. Such deluge of water will provide therequisite agitation and scouring action to cleanse debris from theproduce supported by or located within the baskets. Any dislodged debrisflows with the washing fluid downwardly by gravity through the aperturesin shelf 256 onto filter 270. The filter filters the debris from thewashing fluid and the filtered washing fluid is collected within trough272. Pump 274 draws the filtered washing fluid from the trough andforces expulsion of the filtered washing fluid through the nozzles. Suchwashing action will continue for a predetermined time, as set by thecontrols located upon control panel 308.

Subsequent to draining of the washing fluid on completion of a washingcycle, a quantity of fresh water or rinse solution is introduced to thetrough. The fresh water or rinse solution is pumped through the conduitsand nozzles onto the produce to wash away and rinse any residual washingor cleaning solution from the produce.

Conventional nozzles of the type used for cleansing items with water orliquid spray emit a cone shaped spray pattern 330 which is hollow, asillustrated in FIG. 11. Any item intercepting the spray pattern willhave impinged thereupon an annular band 332 of water or washing fluid.Generally, the droplets 333 forming the spray are relatively small sizedand travelling at a relatively high rate. The resulting kinetic energyof each droplet is relatively high. Because the area of the dropletimpinging upon the item to be washed is relatively small, the force, inpounds per square inch, imposed by the droplet is relatively high. Forcrockery and the like, the destructive effect of this force isinconsequential. For soft tissue items, such as produce, includingstrawberries, other berries, lettuce, etc., bruising and tissue damagewill occur. To obtain a relatively large mass of water or washing fluidimpinging upon the item to be washed per unit of time requires arelatively high velocity of the hollow cone shaped spray pattern. Thehigher velocity or flow rate will contribute to washing or flooding tohelp convey debris and other foreign matter but the likelihood of damageto delicate and soft tissue items being washed due to the increasedforce of the spray pattern is exacerbated.

To avoid the actual and potential damage to soft tissue items beingwashed, such as fruits and vegetables, nozzles 334 of the typeillustrated in FIG. 12 have a spray pattern 336 defining an expandingcone 338 and are used with the produce washers described above. Thespray cone is not hollow as shown by spray pattern 330 illustrated inFIG. 11 emanating from a conventional nozzle. Instead, expanding cone338 is filled with randomly distributed droplets 340 emanating fromnozzle 334. For a given flow rate from each of nozzles 334 and theconventional nozzle producing hollow cone shaped pattern 330, the axialflow rate per area of droplets 340 within the area defined by cone 338is substantially less than the flow rate per area of the droplets withinthe area defined by annular band 332. This reduced flow rate per area ofnozzle 334 over that of conventional nozzles will result in impingementupon the item being washed at a lower force per unit area of thedroplets since droplets are disposed throughout the area of the coneimpinging upon the item being washed and not just within an annular bandof the cone of water. Yet, the quantity of washing fluid impinging uponthe produce may be the same or more than that emanating from aconventional nozzle.

Because individual droplets 340 impinge upon the element being washed,repetitive impact forces will impinge upon debris and other foreignmatter present. Such impacts will tend to agitate, scour and dislodgedebris and foreign matter from the element being washed. As the impactforces are relatively low, damage to the element being washed due to theimpacts is relatively unlikely. The substantial quantity of water orwashing fluid per unit area will tend to cause scouring flotation andcarrying away of dislodged debris and foreign matter. Such agitation,scouring and flotation will be present in crevices, depressions and evenfolds of the element being washed and difficult to clean produce, suchas lettuce and broccoli can be readily cleaned. Because of the lowimpact forces and low probability of damage, soft tissue produce, suchas strawberries and other fruits or vegetables, are readily washed cleanwithout ripping or tearing of the outside skin.

For reasons not fully understood, it has been found useful to add a weakacidic solution to the wash water initially placed within the trough ofthe produce washer. For example, the juice squeezed from half a lemon ora small quantity of lemon abstract along with about a tablespoon ofcommon salt (N_(a) Cl) poured upon the screen or into the trough priorto the washing cycle provides somewhat better cleaning than plain tapwater. This suggested cleaning solution is equivalent to a mildhydrochloric acid solution and is a very effective cleaning solution.Where readily available tap water may be contaminated, it is suggestedthat purified water be used as the washing fluid.

Produce, whether vegetables or fruits, vary significantly in robustness.Moreover, the degree and type of debris and contaminants present varysignificantly. To accommodate such range of variations, the controlpanel of the produce washer provides the capability of varying the waterflow rates through the nozzles to increase or decrease the impact forcesof the impinging droplets. Typically, the flow rate of the recyclingwashing fluid is 7-9 gallons per minute and the pressure at the nozzlesis in the range of 100-110 psi. Usually, only 1 to 11/2 gallons ofwashing fluid is consumed per washing cycle. These ranges of flow rate,pressure and volume would also be applicable to the rinse cycle. Furthercontrols are provided to lengthen or shorten the wash cycle and/or rinsecycle to perform the washing and the rinsing operations as efficientlyas possible.

As representatively illustrated in FIGS. 2 and 4, wires 350 andelectrical conductors or cables 352 may be routed through the spacebetween the exterior walls of the cabinet and the false walls of thecompartment. Similarly, as illustrated in FIGS. 5, 7 and 10, conduits ofplumbing trees 92, 140 and 170, may be routed in the spaces between theexterior walls of the cabinet and the false walls of the compartment.The pump and associated valving, when present, may be located in thespace between the bottom of the trough and the bottom of the cabinet.The electrical conductors, the respective locations of any electricalconnectors, the plumbing conduits and plumbing fixtures are shieldedfrom the water or washing fluid by the false walls of the compartment incombination with the seals disposed about the nozzles and relatedstructure at the point of penetration into the washing compartment.

While the principles of the invention have now been made clear in anillustrative embodiment, there will be immediately obvious to thoseskilled in the art many modifications of structure, arrangement,proportions, elements, materials and components used in the practice ofthe invention which are particularly adapted for specific environmentsand operating requirements without departing from those principles.
